hey guys,
could you help me with this question? (3D Trig)
From a boat A, due wast of a cliff, the angle of elevation of the top of the cliff is 26 degrees. From another boat B, which is a bearing of 150 degress from the cliff, the angle of elevation of the top of the cliff is 20 degrees. If the two boats are 520 metres apart:
(i) show that angle AFB=60 degrees, where F is the foot of the cliff
(Would be nice if you could also computer-draw a diagram of this)
thanks
